BOTTLE crosun'n- Application filed- May 11,

This invention relates to bottle closures of the type disclosedin myco-pendingapplication for United States Letters Patent Serial No. 17 7,1 17 filed-March 21st, 1927, of-which co-pending applicationthe presentapplica tionforms acontinuation, in part; As set forth inmy'abovementioned. co pending application, the-present invention re lates tosanitary bottle closures of that kind embodying a disk member adapted tobe seatedwithin the mouth of the bottle, and a cap member carrying thedisk member and having a marginal rimor flange adapted to fit over themouth of the bottle to effectively prevent entrance of'dirt andotherlforeign matter into the bottle and consequent con-- tamination ofthe bottle=contents.

More particularly, the present application is directed to certain formsof bottle closures,

0 of the above kind'wherein'the cap member has a flat top wall,and'whereinmeans is provided for cooperation with said top wall toprevent nesting of the closures" when a plurality of the same are arranged insuperimposed rela- -tion within the feed hopper of. a bottle cappingmachine, and wherein thecap member and disk are so associated as toprovide for efiicient' application of the closure to the bottle i l 4 .1r

Referring more in detail ito the drawings, the present bottleclosure'essentially embodies a cap member 5'having' a normally" flat topwallandprovided' with a dependingrim 6, a closuredisk 7 attached'to theunderside of'said top wall, a circular part or ring 8 attached to'theunderside of and depending from the top wall of the cap member 5, said"circular part or ring -8 being adapted to receive-thepressure ofta dieinthe application Figure IO-and. having direct-pressure contact with themargin oft-he closure disk 7: as in? dicatedat 10. The-ring ordependin'gpart: 8 is therefore located. above the marginali portion of the'closured-isk 7 imposition to: enable disk 7 into proper seating contactwith" the internal shoulder: 11 usually provided inthe mouth of the milkbottle 12'.

As the top wall; of the: capmember: 5. is; normally flat the" portionthereof; within. the ring 8is-inthe'same horizontal plane: with: themarginalporti'on of said topwallout:- wardly'ofs'the ring18. The closuredisk7 is; providedinwardly of its. margin with ads the same horizontalplane with the lower edge of the rim 6 and adapted to rest upon thecentral portion of the top wall of the cap member 5 of anothersimilarclosure disposed therebeneath for preventing nesting of saidclosures. It is thus apparent that a plurality of the closures may bereadily placed in superimposed relation within the feed hopper 14 of abottle capping and filling machine as shown in Figure 11, with thelowermost closure readily displaceable from beneath those disposedthereabove under the action of the usual ejecting plunger 15. Unhamperedfeeding of the caps successively from the bottom of the hopper forapplication to successive bottles is thus effectively insured.

A relatively small spacer disk 16 may be secured between the centralportions ofthe top wall of the cap member 5 and the closure disk 7 inspaced concentric relation to and within the ring 8, thus enabling thecontact pressure of the capping die to be directly transmitted from thecenter of the top wall of the cap member 5 to the center of the closuredisk 7 whereby the closure may be caused to dish downwardly to the formof Figure 10, upon application of the closure to the bottle. In thisway, most eflicient seating of the closure disk 7 within the mouth ofthe bottle is insured, with the closure disk under such tension as toresiliently :retain itself in place in a general manner Well known inconnection with the ordinary bottle closure embodying merely a closuredisk. This flexing will obvi -'ously be effected by providing thecentral provided for such attachment. However, the

ring 8 and spacer 16 are preferably glued or adhesively fastened to theunderside of the top wall of the cap member 5 and have the closure disk7 suitably fastened thereto. In each instance or form of the invention,the closure disk 7 is preferably provided with a peripherallocking'projection or annular flange as at 17 adapted to engage the seat11 in the mouth of the bottle 12. It will be apparent that the circularconnecting member or ring 8, which is preferably of card board, is openat the center, thus leaving the major portion of the disk7 free andunattached to the top wall of the cap me1nber'5, whereby the disk 7 iscapable of beingreadily flexed downwardly as mentioned above andillustrated in Figure 10. The pressure applied at 9 over the ring 8 isat a point within the area of the opening of the milk bottle mouth, andthe disk 7, being of slightly greater diameter than said opening, willbe firmly seated and retained in place by the natural resiliency of thedisk 7.

In the form of the invention shown in Figures 1 and 2, the dependingpart 13 consists of a central circular depressed portion of a relativelythin disk 18 secured at its margin to the undersurface of the marginalportion of the closure disk 7.

In the form of the invention shown in Figures 3 and 4, the dependingpart 13 is a circular central depressed portion of the disk member 7itself, while in Figures 5 and 6, such depending parts consist in aplurality of studs 19 comprising small disksof cardboard secured byadhesive to and depending from the undersideof the disk member 7. I Inthe form of the invention shown in Figures 7 and 8, the construction isthe same as shown in Figures 3 and t, except that the projectingmarginal portion 20 of the closure disk 7 is directed upwardly in theform of an annular flange encasing and secured to the outer peripheryofthe ring or connecting member 8.

In the form of the invention shown in Figures 9 and10, the constructionis the same as shown in Figures 1 and 2, except that the dependin part13 comprises a relatively thick disk 0 pasteboard secured centrally tothe i underside of the disk member 7 andhaving a diameter considerablysmaller than the latter.

Minor changes may be made without de parting from the spirit and ventionas claimed.

What Iclaim as new is 1; A bottle closure including a cap memberembodying a substantially flat top wall having a depending rim, aclosure disk spaced from and attached to the under side of said topwall, and a circular ring located between and having direct pressurecontact with said top wall and the margin of said closure disk, saidring being adapted to transmit the pressure of a die from the contiguousportion of the top wall to the margin of said closure disk in theapplication of the closure to the bottle, said closure disk beingprovided inwardly of its margin with a depending por tion locatedsubstantially in the same horizontal plane with the lower edge of therim.

2. A bottle closure including a cap mem ber embodying a substantiallyflat top wall having a depending rim, a closure disk spaced from andattached to the under side of said top wall, a circular ring locatedbetween and scope of the inhaving direct pressure contact with said topwall and the margin of said closure disk,

said ring'being adapted to transmit the pres-' tle, said closure diskbeing provided inwardly latter in the application of the closure to thebottle.

3. A bottle closure including a cap member embodying a substantiallyflat top wall having a depending rim, a closure disk spaced from andattached to the under side of said top wall, a circular ring locatedbetween and having direct pressure contact with said top wall and themargin of said closure disk, said ring being adapted to transmit thepressure of a die from the contiguous portion of the top wall to themargin of said closure disk in the application of the closure to thebottle, said closure disk being provided inwardly of its margin with adepending portion located substantially in the same horizontal planewith the lower edge of the rim, said closure disk having a peripheralportion projecting outwardly slightly beyond the periphery of said ring.

4:. A bottle closure including a cap member embodying a substantiallyflat, top wall having a depending rim, a closure disk spaced from andattached to the under side of said top wall, and a circular ring locatedbetween and having direct pressure contact with said top wall and themargin of said closure disk, said ring being adapted to transmit thepressure of a die from the contiguous portion of the top wall to themargin of said closure disk in the application of the closure to thebottle, said closure disk being provided inwardly of its margin with adepending portion located substantially in the same horizontal planewith the lower edge of the rim, said closure disk having a centraldepressed part forming said depending portion.

In testimony whereof I mix my signature.
